I installed Windows 8 Pro on a Zotac Zbox AD03 3 days ago. The installation went fine and everything, including the network and internet, worked just fine. The network contains 4 Windows 7 machines, a network printer, a Buffalo NAS, a Windows Home Server, a 16 port switch and a Motorola combo cable modem (DOCSIS 3.0) and router. The new computer with Windows 8 could see everything and appeared to function perfectly with normal internet access. After powering it off for the night I restarted it the next morning and found it could only see the Windows Home Server and one of the Windows 7 machines. It reported that it was not attached to a network and when I tried to connect I got error 651. I did a complete new install and it still could only see the Windows Home Server and the same other Windows 7 machine and still get the error 651 message. What could have happened during that power down/restart to cause it to lose network connectivity? How do I fix it?

Hello Alan,
I would suggest you to perform a System Restore and then check how it works.
If it works fine, then install the driver manually one by one.
Refer to the link “How to restore, refresh, or reset your PC” to know how to perform System Restore.

I would suggest you to download and install the latest Wireless LAN driver for Windows 8 from the manufacturer’s website and then check how it works.

I had looked on the Lenovo site but couldn't nail down the page you connected me too.
I have downloaded the driver and will let you know how it goes.
hello again.
an update to the operation of the laptop is as follows . 5 days of trouble free connectivity followed the installation of the Lenovo software driver update then on Thursday there were some windows updates installed. since then there has been terrible connectivity only connecting 1 time in 5 on average. resetting the network adaptor etc in troubleshooting gives no joy.
if I plug the wifi dongle in it pushes straight onto the internet router instantly. so it appears there is some conflict internally again. it is worst at busy internet usage times of day.

- What is the make and model number of the laptop?
Laptop must be having inbuilt Wi-Fi adapter in it. I would suggest you to check the laptop user manual to know how to turn on the Wi-Fi port.
Perform the troubleshooting steps from the link “Wired and wireless network connection problems in Windows” and then check if you are able to connect to router.
I hope this helps you to fix the issue. If the issue persists or you have any other issues with Windows please do post it in Microsoft Community. We would be happy to help you.
as I said the Wi-Fi on the inbuilt adaptor works most of the time now . it only seems to refuse to connect about 20% of the time its a Lenovo ideapad z585 running windows 8.
